A contactless dielectric constant sensing system based on a split-ring resonator-loaded monopole
Carnerero Cano, Javier; Galindo Romera, Gabriel; Martínez Martínez, José Juan; Herraiz Martínez, Francisco Javier (2018-06-01)In this paper, a low-cost contactless passive sensor is designed and manufactured. The structure consists of a short-circuited printed monopole antenna coupled to two split-ring resonators. The permittivity of the materials ... -
A contactless system for the dielectric characterization of liquid drop
Galindo Romera, Gabriel; Carnerero Cano, Javier; Martínez Martínez, José Juan; Rivera Lavado, Alejandro; Herraiz Martínez, Francisco Javier (2020-08-31)The present article shows the design, implementation, and measurement of a compact contactless electronic system for sensing small volumes of liquids. The system is based on two elements: an electronic reader and a passive ...
